Atto is a simple but popular synthetic benchmark for testing the maximum theoretical speed of storage devices. In this test the read speed of the Apex SSD drive considerably outperforms all of the mechanical drives, even our RAID 0 array. The Scorpio Black, one of the fastest mechanical drives for notebooks is almost 4 times slower than the Apex SSD drive.

HD Tune is a benchmark able to show the sequential read speed across the entire capacity range. Mechanical drives get slower as the data is being moved towards the edge of the platters, in this test they start with their maximum sequential read speed and end with the minimum. This is not the case for SSD drives however as they have no rotating platters or other moving parts therefore they can sustain maximum speed across the entire data range.

Once again the performance of the Apex drive greatly outpaces that of the mechanical drives. Even though our AAKS RAID 0 array appears able to compete with the transfer speeds of the Apex, the access times are 40 to 60 times slower. It is also noteworthy to mention that the access time the mechanical drives need in order to access data increases as their data moves towards the edge of the platter, while the OCZ drive has a steady and miniscule access speed across the entire data range.

Sandra is one of the most popular synthetic benchmarking suites. Here the OCZ Apex Series SSD drive maintains a constant speed ratio of 173.54MB/s when installed on our Intel P35 based motherboard. The single mechanical drives cannot compete with the small SSD drive, and even though the AAKS RAID array can reach the Index speed of the Apex it still falls far behind when it comes to the data access times. Unfortunately this benchmark cannot identify random access times below 1ms and all devices with a <1ms random access speed are simply rated as 1ms.

Futuremark’s PC Mark 07 is a benchmark which is trying to emulate real-world situations such as the windows start-up and the windows defender scanning routine in order to test the performance of HDD drives. In this benchmark we can see the OCZ Apex drives completely annihilating the mechanical drives in all but two tests. It seems that the extremely quick seek times of the Apex drive give it more than an edge when it comes to application loading, scanning or the OS start-up.
